摘　　要：对青藏高原地区Trombe墙式太阳房室内外空气温度、水平面和南立面太阳直射散射辐射强度、集热蓄热墙夹层温度分布、通风孔风速和风温，墙体热流等参数进行测试。通过对测试数据分析，认为：Trombe式太阳房具有较好的集热和蓄热性能；通风孔在日出后2—3h开启、日落前1h关闭效果最佳；该地区Trombe墙日平均热效率可达69．7％；节能率可达72．8％。The outside and inside air temperature, total and diffuse solar radiation intensity of horizontal and vertical plane of passive solar house with Trombe wall, the air layer temperature distribution, the temperature and velocity of air in vents, and heat flux of Trombe wall were measured in the Qinghai-Tibet Plateau region. The measuring analyses show that the passive solar house with Trombe wall has well heat-collecting and heat storage properties, and opening the vent of Trombe wall 2-3 hours later than the sunrise time and closed 1 hour earlier than sunset time more reasonable; the average heat efficiency and energy saving fractional can reach 69.7% and 72. 8% respectively.
